Seminar - Andreas Malcherek - Some advances in sediment transport modeling: Fluid mud rheology long term morphological simulations

Friday 23 March, 1.00 pm - 2.00 pm
Civil Engineering Lecture Room 3

Prof. Dr.-Ing. Andreas Malcherek
Armed Forces University Munich

Abstract:
In this presentation two recent developments in sediment transport modeling will be presented: For the simulation of fluid mud dynamics in harbours and estuaries a rheological model is presented basing on the shear rate and the solid matter/water ratio. Using this rheological model the Cauchy equations are solved on a isopycnical grid i.e. a grid with a vertical discretisation depending on constant density surfaces. The scheme is implemented in the semi-implicit UnTrim-code of V. Casulli.

In the second part of the presentation a long term simulation is presented for the tide resolved morphodynamics of the North Sea taking into account sediment transport under tidal currents, waves as well as dredging/dumping operations for 100 years. The simulation is done with the Telemac-System.
